Answer:
Acute angle
Step-by-step explanation:
Given that m<C =
, to find out the type of angle angle C is, evaluate the expression given by substituting x = 13, in the expression.
m<C = 
m<C = 
m<C = 
m<C = 76°
Acute angles are less than 90°.
m<C is less than 90°, therefore it is an acute angle.
If I’m assuming that symbol next to the C at the end of the question means C mirrored the the answer would be (3,1) but I’m not quite sure what it means
The total cost would be:
$20 = two people- 2*20=40$
20 = guest
20*20=
400 would be the cost
